Mölndal's air quality is generally good by Swedish and European standards, with only occasional local peaks in pollutant levels. Emissions locally trace mainly to pharmaceuticals and tech and the traffic passing through the town centre. The natural airflow associated with the Mölndalsån river valley works in the area's favour for keeping pollutant levels down. As a result, Mölndal rarely records air quality readings that would concern most residents.

When is air pollution at its worst in Mölndal?
How does air quality change throughout the year in Mölndal? Midwinter is generally the least favourable period, as still air and cold temperatures allow local pollutants to build up rather than clear. Spring usually marks a turning point, with more active weather systems reducing how often pollutants can accumulate. Air quality is typically strongest in summer, helped by more wind and sunshine, though still days can occasionally push up ozone levels. By October and November, cooling air and calmer evenings start to mirror the patterns that intensify further in winter. The comparatively mild southern Swedish climate means these seasonal swings are usually less pronounced than further north.
Are air quality levels in Mölndal based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
